If you care about your health, filtering your household water is more a necessity than an option these days. Water pollution has become a very significant problem that simply cannot be ignored any longer.
It doesn't matter where you live, as many of the most dangerous chemicals find their way into the ecosystem and food chain, spreading from one continent to another, as described in a recent article by Prevent Disease.1
Fish and other wildlife are demonstrating the ramifications of out of control water pollution, and there's cause to believe chemical pollution may be affecting human health as well, even if the effects are not always as directly traceable.
The sources of pollution are many, ranging from agricultural runoff and industrial releases, outworn pipes, firefighting foam and pharmaceutical drugs, and even the chemicals used during water treatment themselves."
